Research on the application of various foundation treatment techniques in the construction of deep and weak foundations
To further promote the application of composite pile net structure in road engineering,this paper reviews the foundation treatment practice of a large-scale deep and weak foundation engineering project.Firstly,the construction principle of the composite pile net struc-ture is analyzed and introduced.Based on the project overview,roadbed quality control standards,and construction difficulties,the specif-ic construction plan of the project is determined.On this basis,the construction process and methods of the plan were analyzed,and the key points of quality control during the construction process were summarized and discussed.By monitoring the completed road construc-tion,it was found that the combined pile network structure treatment technology in the plan can effectively handle the problems caused by large areas of deep and weak foundations,and has good settlement control capabilities.
